Suitable materials include specifically, but not exclusively thin plasticized plastics such as a clear polyester film available from Tekra Corporation of New Berlin, Wisconsin under the mark MELINEX 1311. Other suitable materials include specifically, but not exclusively, metals, cellulose based plastics and cardstock. Such modifications and other modifications that, for example, alter the shape of the snap-bucklable member 104 (some of which are described in other embodiments below), are within the scope of this invention. [0032] The overall size and shape of the bandage 100 can vary depending on the application.
  • a bandage 100 that is 2 inches long and 1 inch wide could be suitable for some applications such as stopping the bleeding of venous puncture wounds on the arm (not shown) from injections or catheters (not shown).
  • a bandage 100 that is 8 inches long by 4 inches wide could be suitable.
  • Other lengths and widths could also be suitable. The appropriate size could largely depend on the part of the body for which the bandage 100 is intended and the amount of pressure needed.
  • the shape of the bandage 100 can also vary depending on the application. While the bandage 100 shown in FIG. 1 is rectangular in shape, the bandage 100 may take on any of the various shapes well known in the art of bandages.
  • the bandage 100 can be held onto a surface (not shown) such as the skin (not shown) in different ways.
  • the bandage 100 disclosed here uses adhesive on the interior side 106 of the backing 102.
  • various other means of fastening including hook and loop fasteners, straps, buttons, hooks, etc., in combination with wraps, for example, can be employed. Such modifications can still be within the scope of this invention.
  • the manufacture of the bandage 100 can be accomplished in a variety of ways. For many applications, it can be preferable to have some portion or all of the cutting and assembly of the bandage 100 completed using a web converting process.
  • the pad 101 and the backing 102 can be cut using a rotary die and bonded to each other using adhesives in such a process.
  • the snap-bucklable member 104 can also be manufactured and placed into the bandage 100 using a web converting process.
  • FIG. 4 shows a sheet 108 of material suitable for use in forming snap-bucklable members 104, such as PET.
  • the snap-bucklable members 104 can be conveniently formed in a stamping operation (with the application of heat). The snap-bucklable member 104 can then be cut along line 109 and inserted between the backing 102 and the pad 101 during the web converting process.
  • the bandage 100 can be constructed and manufactured in many different ways. Although a web converting process is described above, various manufacturing techniques including assembly by hand can be employed. Bonding techniques other than adhesives can be used. For example, heat can be used to melt layers together or mechanical fasteners can be used to fasten components together. Such modifications are still within the scope of this invention.
  • the bandage 100 as disclosed above can have many uses and offer several advantages including the following.
  • the bandage 100 can be a more sterile and more efficient means to apply light pressure to wound sites to stop bleeding. For example, when a patient receives an injection such as for immunization, a venous puncture wound is typically created. Oftentimes, a caregiver will combine a cotton ball and tape to apply pressure to the wound site (not shown).
  • a pressure bandage 100 (that can be efficiently sterilized during manufacture) can be used instead of tape and a cotton ball for wound sites such as venous puncture wounds.
  • the bandage 100 can be used for various other reasons, such as limiting blood flow.
  • the pressure bandage 100 can be applied to a vein or artery.
  • FIGs 5 and 6 show a pressure bandage 200 according to a second embodiment.
  • the bandage 200 includes a pad 201, backing 202 and a snap-bucklable member 204 generally in accordance with the first embodiment, but with at least two differences.
  • the bandage 200 according to the second embodiment can have a small frangible container 210 resembling a gel capsule or an ampoule containing a unit dose, for example a dose of a flowable material such as a liquid medication or other beneficial substance.
  • the snap-bucklable member 204 in this embodiment is an arch-shaped member rather than a dome-shaped member.
  • the pressure bandage 200 as shown in FIG 5 has an interior side 206 that generally faces toward the body (not shown) of a wearer (not shown) of the bandage 200.
  • the bandage 200 also has an exterior side 207 that generally faces away from the body (not shown) of the wearer (not shown) of the bandage 200.
  • the snap-bucklable member 204 By pressing on the arch shaped snap-bucklable member 204 the snap-bucklable member 204 can be inverted, just as the dome shaped snap-bucklable member 104 of the first embodiment was inverted.
  • pressure is exerted upon on the frangible container 210, causing the container 210 to burst and release liquid medication or other beneficial substance (not shown) stored in the container 210.
  • the liquid could then partially or fully soak into the pad 201.
  • the pad 201 can also be impregnated with a medication or beneficial substance, such as a medication that can act in combination with a liquid released from the container 210.
  • the frangible container 210 can be made of different materials. Various kinds of gels or plastics can be preferable for many applications. For most applications the container should have a low bursting strength. Glass and brittle plastics are traditionally used for ampoules, but may not be suitable for most applications because of the potentially sharp edges. To make bursting the container 210 easier, a small point (not shown) can be incorporated into the snap-bucklable member 204 to prick the container 210 when pressure is applied to the snap-bucklable member 204.
  • the bandage 200 as disclosed above can offer advantages including the following.
  • First, the bandage 200 can offer a convenient way to store a liquid such as a medication in a bandage 200 without wetting the entire bandage 200.
  • Second, the bandage 200 can offer a way to release the liquid from the bandage 200 when desired. For example, when the bandage 200 is positioned over a wound (not shown) on the body (not shown).
  • Third, the bandage 200 can offer a way that materials can be mixed for application to the skin (not shown) at an appropriate moment. For example, it may be desirable to have materials mixed after the bandage 200 is applied to the body (not shown). This might be especially true, for example, for materials that do not have a sufficiently long shelf life in a mixed form.
  • Fourth, the bandage 200 can offer a way to use an existing form of container 210 (e.g., a gel capsule) for use with a bandage 200.
  • FIGs 7, 8A and 8B show a bandage 300 according to a third embodiment.
  • the bandage 300 includes a backing 302 and a snap-bucklable member 304 generally in accordance with the first and second embodiments, but with certain differences.
  • the bandage 300 according to a third embodiment can be constructed without a pad.
  • the container 310 can be formed differently than the container 210 discussed above in relation to the second embodiment.
  • the container 310 for the flowable material 320 in this embodiment employs a seal 315 over the open end (unnumbered) of the dome-shaped snap-bucklable member 304 to form a retention chamber (unnumbered) for the flowable material 320.
  • the flowable material 320 may be in liquid, powder, or granular form.
  • FIGs 8A and 8B show the container 310 formed by the dome-shaped snap bucklable member 304 and the seal 315 in isolation.
  • FIG. 8A shows the sealed container 310 holding a flowable material 320
  • FIG. 8B shows that same container 310 after the snap- bucklable member 304 has been inverted so as to break open the seal 315 and release the flowable material 320.
  • the flowable material 320 is released because inverting the snap- buckling member 304 increases pressure on the seal 315 to an extent that the seal 315 burst as shown in FIG. 8B.
  • the pressure bandage 300 as shown in FIG 7 has an interior side 306 that generally faces toward the body (not shown) of a wearer (not shown) of the bandage 300.
  • the bandage 300 also has an exterior side 307 that generally faces away from the body (not shown) of the wearer (not shown) of the bandage 300.
  • the seal 315 can be made of various materials. For many applications a medical grade gelatin film or a wax film can be suitable.
  • the bandage 300 as disclosed above can offer advantages including the following.
  • First, the bandage 300 can be conveniently manufactured without a pad. The absence of a pad can permit a more direct application of the flowable material 320 to the * skin (not shown), can speed the intended action of the flowable material 320, can make manufacture less expensive, and can reduce the bulk of the bandage 300.
  • Second, the dome-shaped snap- bucklable member 304 can form part of the container 310. This can reduce the bulkiness of the bandage 300 and potentially make the release of the flowable material 320 easier.
  • FIGs 9 A and 9B show a portion of a bandage 400 according to a fourth embodiment.
  • the bandage 400 includes a backing 402 and a snap-bucklable member 404 generally in accordance with the first, second and third embodiments, but with certain differences.
  • a plunger 425 is provided so as to cooperate with the snap-bucklable member 404. While the snap-bucklable member 404 and the plunger 425 are shown in FIGs 9A and 9B as two distinct parts, they also could be formed as a unitary piece.
  • the face of the plunger 425 can have a covering 426.
